Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a display panel for mounting to canopy
supports on a golf cart.
2. Description of the Related Art
The sport of golf has grown significantly over the past decade in
terms of public interest and participation as a recreational sport.
In many markets there is a lack of capacity in the number of golf
courses to handle the increased demand of golfers and securing a
tee time is difficult at best. Golf courses are being built at a
rate not seen in the past in order to serve a higher per capita
percentage of the population.
The typical golfer reflects a high-end demographic with the
financial means to afford a wide range of products and services.
The golf audience is therefore a market that is very appealing to
many businesses for advertising goods and services. Assuming a
typical round of golf takes about five hours to play and that most
golfers playing twice a week if not more, it would be desirable to
present advertising to a golfer during the course of play of a
round of golf. The advantage of such advertising is that a message
is targeted to a desirable demographic audience that is captive for
an extended period of time resulting in a lasting impact. This
length of impression likely cannot be found with other media
venues, for example, newspaper, magazine, or billboard
advertising.
Some devices have been suggested for reaching such an audience on
the golf course. One system in particular is described in U.S. Pat.
No. 6,367,181. This reference describes a display panel for
attaching to a golf cart with two frames in which advertising
messages can be displayed. A partitioned frame is sandwiched
between two transparent panel sheets, which are held together by
screws or bolts through a plurality of holes drilled through the
perimeter of the display panel. Significant disadvantages of this
system include the exposure of the advertising material to moisture
seeping into the display panel through the bolt holes and seams
between the frame and transparent panels and other ink and paper
degrading weather conditions; the instability of the mounting
methodologies; and the difficulty of removing and replacing the
advertising messages within the display panel.
The information included in this Background section of the
specification, including any references cited herein and any
description or discussion thereof, is included for technical
reference purposes only and is not to be regarded subject matter by
which the scope of the invention is to be bound.
SUMMARY OF THE INVENTION
The present invention is an improved golf cart display panel that
is substantially moisture resistant. The golf cart display panel of
the present invention further protects the display materials
exhibited therein from the damaging effects of solar radiation. In
addition, the golf cart display panel is designed to provide
simple, easy access to remove and replace the display
materials.
In one embodiment of the invention, a golf cart display panel is
composed of a first transparent panel, a second transparent, at
least one fixed spacer member positioned between the first
transparent panel and the second transparent panel and a removable
spacer member functionally positioned between the first transparent
panel and the second transparent panel. The first transparent panel
is adhered to a perimeter of the at least one fixed spacer member.
The second transparent panel is adhered to the perimeter of the at
least one fixed spacer member. A cavity is defined between the
first transparent panel, the second transparent panel, and the at
least one fixed spacer member. The removable spacer member seals
the cavity when positioned between the first transparent panel and
the second transparent panel and affords access to the cavity when
removed from between the first transparent panel and the second
transparent panel.
The golf cart display panel may further be composed of a first
frame member and a second frame member. The first frame member is
adhered to the first transparent panel opposite the at least one
fixed spacer member. The second frame member is adhered to the
second transparent panel opposite the at least one fixed spacer
member. In addition the golf cart display panel may also be
composed of a first clamp attached to a first lateral end of the
display panel and a second clamp attached to a second lateral end
of the display panel.
In another embodiment of the invention, a weather-resistant golf
cart display panel is composed of an elongate container having
opposing transparent walls. The elongate container defines a cavity
accessible via a single opening in one lateral end of the elongate
container. The cavity is adapted to house a flat display sheet.
Excepting the single opening, the elongate container is impervious
to moisture. A spacer member is adapted for insertion into the
single opening. The spacer member substantially seals the cavity
from ingress of moisture. A pair of clamps are attached
respectively to each lateral end of the elongate container and are
adapted to connect to a canopy support of a golf cart.
In yet another embodiment, the invention is directed to a method
for removing and replacing a display sheet within a golf cart
display panel. In this method a single frame member is removed from
the display panel. The display sheet is withdrawn from within a
cavity in the display panel through an opening into the cavity
formed by removal of the single frame member. A new display sheet
is inserted into the cavity. The single frame member is then
replaced in the display panel.
Other features, details, utilities, and advantages of the present
invention will be apparent from the following more particular
written description of various embodiments of the invention as
further illustrated in the accompanying drawings and defined in the
appended claims.

DETAILED DESCRIPTION OF THE INVENTION
The present invention is directed to an improved display panel for
attachment to a golf cart. The display panel may be used to provide
advertising, identification, or other information to golfers riding
the cart, to other golfers on the course, or to the public in
general.
As shown in FIG. 1, a display panel 2 according to one embodiment
of the present invention may be mounted to a pair of canopy
supports 6 on a golf cart 4. Generally, a pair of canopy supports 6
extend upward from the front of the golf cart 4 to support the
front edge of the canopy 5 or roof of the golf cart 4. (All
references to direction used herein are made with respect to the
golf cart 4 as viewed from the front end. Therefore, the "right" is
the side with the steering wheel.) Similarly, a second pair of
canopy supports 6' extend vertically from the rear of the golf cart
4, usually from behind the seat-back in order to support the rear
of the canopy 6. The display panel 2 of the present invention spans
the width of the canopy supports and is mounted at each lateral end
to a respective canopy support 6.
It should be apparent from FIG. 1, although not explicitly shown,
that the display panel 2 may be mounted at any point along the
height of the canopy supports 6. However, it is desirable at the
display panel 2 not interfere with the field of vision of a golfer
driving the golf cart 4. Therefore, the display panel 2 is
preferably located either at the top of the canopy supports 6 near
the canopy 5 like a visor or below the height of the steering
wheel, thereby affording the golfer driving the golf cart 4 a clear
field of vision. Alternatively, although perhaps less desirable,
the display panel 2 may be mounted at any point along the height of
the rear canopy supports 6', most likely adjacent the canopy 5 in
order not to be obscured by any golf bags secured to the rear of
the golf cart 4.
The assembly of the display panel 2 and its various components are
shown in greater detail in FIGS. 2 10B. The display panel 2 is
primarily composed of a front frame member 8, a rear frame member
10, a rear transparent panel 12, a front transparent panel 14, and
a collection of spacer members. As shown to good advantage in FIG.
4, the spacer members include a top spacer member 16, a right
spacer member 18, a left spacer member 20, and a bottom spacer
member 22. The display panel 2 is also provided with a pair of
support clamps 24 affixed to the top lateral edges of the front
side of the display panel 2. In this embodiment, the display panel
2 is configured as an elongate rectangle of a width long enough to
span the distance between the front canopy supports 6 of the golf
cart 4. The height of the display panel 2 is significantly less
than its width and may be chosen to be of a height adequate for
presentation of display material, but not too tall so as to obscure
the view of the driver of the golf cart 4.
The front frame member 8 is shown in exemplary detail in FIGS. 5A
and 5B. The front frame member 8 is composed of a top frame wall
50, a bottom frame wall 52, a right frame wall 54, and a left frame
wall 56. The frame walls together define a rectangle which further
defines a frame opening 48 in the front frame member 8. The top
frame wall 50 further defines a right clamp bolt hole 40e and a
left clamp bolt hole 42e positioned respectively toward the
opposing lateral ends of the top frame wall 50. The left frame wall
56 also defines a left spacer bolt hole 46e, generally centered
within the left frame wall 56. The left frame wall 56 further
defines a tab recess 44d along the left edge of the left frame wall
56. Each of the front frame member 8 and the rear frame member 10
is identical to the other. Thus, while only the front frame member
8 is described in detail, each of the attributes described with
respect to the front frame member 8 is equally applicable to the
rear frame member 10. As, the rear frame member 10 is
interchangeable with the front frame member 8, the rear frame
member 10 thus defines identical apertures including a right clamp
bolt hole 40a, a left clamp bolt hole 42a, a left spacer bolt hole
46a, and a tab recess 44a. (See, e.g., FIG. 4.)
The rear transparent panel 12 is depicted in detail in FIGS. 6A and
6B. The rear transparent panel 12 is a thin flat panel of generally
rectangular configuration. Adjacent a top edge of the rear
transparent panel 12 are a right clamp bolt hole 40b adjacent to
the right-hand side of the rear transparent panel 12 and a left
clamp bolt hole 42b adjacent to the left-hand side of the rear
transparent panel 12. Along the left edge of the rear transparent
panel 12 is a semi circular tab recess 44b. Also along the left
edge of the rear transparent panel 12 is a spacer bolt hole 46b.
Each of the rear transparent panel 12 and the front transparent
panel 14 is identical to the other. Thus, while only the rear
transparent panel 12 is described in detail, each of the attributes
described with respect to the rear transparent panel 12 is equally
applicable to the front transparent panel 14. As, the front
transparent panel 14 is interchangeable with the rear transparent
panel 12, the front transparent panel 14 thus defines identical
apertures including a right clamp bolt hole 40d, a left clamp bolt
hole 42d, a left spacer bolt hole 46d, and a tab recess 44c. (See,
e.g., FIG. 4.)
In addition to the frame members and the transparent panels, a
collection of spacer members are used to form the display panel 2.
FIGS. 7A and 7B depict a top spacer member 16, which is a long,
thin, rectangular member defining a right clamp bolt hole 40c
adjacent the right end and a left clamp bolt hole 42c adjacent the
left end of the top spacer member 16. A bottom spacer member 22 is
depicted in FIGS. 8A and 8B. The bottom spacer member 22 is
generally the same as the top spacer member 16 in terms of its
rectangular shape and is the same length and width as the top
spacer member 16. However, the bottom spacer member 22 is solid and
does not define any holes or other apertures within its body. The
top spacer member 16 and the bottom spacer member 22 are equal in
length and are equal to the length of each of the top and bottom
edges of the frame opening 48 in the front frame member 8 and rear
frame member 10.
FIGS. 9A and 9B depict a left spacer member 20. The left spacer
member 20 is rectangular in shape, is the same height as the frame
members and the transparent panels, and is the same width as the
left frame wall 56 of each of the front frame member 8 and rear
frame member 10. The left spacer member 20 further defines a spacer
bolt hole 46c, which may be positioned centrally within the left
spacer member 20. The right spacer member 18, depicted in FIGS. 10A
and 10B, is generally identical to the left spacer member 20 in
size and shape. The right spacer member 18 is the same height as
each of the frame members and transparent panels and is the same
width as the right frame wall 54 of each of the front frame member
8 and the rear frame member 10. However, the right spacer member 18
is solid and does not define an aperture as defined in the left
spacer member 20.
The top spacer member 16, the bottom spacer member 22, the left
spacer member 20, and the right spacer member 18 may be positioned
with respect to each other to form a rectangular panel. (See, e.g.,
FIG. 4.) The top spacer member 16 is positioned between the left
spacer member 20 and the right spacer member 18 adjacent the top
edge of each of the left spacer member 20 and the right spacer
member 18. Similarly, the bottom spacer member 22 is positioned
between the left spacer member 20 and the right spacer member 18
adjacent the bottom edge of each of the left spacer member 20 and
the right spacer member 18. This component panel thus formed is
generally the same size and shape as each of the front frame member
8 and the rear frame member 10. In an alternate embodiment (not
shown), the top, bottom, and right spacer members could instead be
a unitary structure defining an open, U-shaped space that to be
capped by a separate left spacer member.
The construction of the display panel 2 is depicted in greater
detail in FIG. 4. The top spacer member 16, right spacer member 18,
left spacer member 20, and bottom spacer member 22 are arranged
into a rectangle defining a space of the same size as the frame
opening 48 and are placed between the rear transparent panel 12 and
the front transparent panel 14. The front frame member 8 is placed
adjacent the front transparent panel 14 and the rear frame member
10 is placed adjacent the rear transparent panel 12. Each of the
right clamp bolt holes 40 in the components of the display panel 2
are aligned concentrically with each other. Similarly, each of the
left clamp bolt holes 42 in the components of the display panel 2
are aligned concentrically with each other. Likewise, each of the
spacer bolt holes 46 is aligned with adjacent spacer bolt holes and
each of the tab recesses 44 is aligned with the other tab recesses,
respectively. In this manner a sandwich of five layers is created
to form the display panel 2.
In an exemplary embodiment, each of the frame members, transparent
panels, and spacer members is composed of an acrylic sheet
material, for example, poly methyl methacrylate. Acrylic sheet
materials are generally weather-proof, fade resistant, and scratch
resistant. Various commercial embodiments of such acrylic materials
include Acrylite.RTM.FF (Cyro Industries, Inc.), Plexiglas.RTM.
(Atoglas Atofina Chemicals, Inc.), and Lucite.RTM. (Lucite
International). The acrylic sheet material used to make the
components of the display panel 2 may be between 1/16'' and 1/8''
or thicker. While the rear transparent panel 12 and the front
transparent panel 14 are clear or transparent sheets as indicated,
the front frame member 8, the rear frame member 10, and each of the
spacer members may be opaque in color in order to provide a visual
frame border around the transparent panels.
Additionally, it is desirable to use an acrylic sheet material that
filters ultraviolet (UV) radiation in order to protect the display
material viewed through the transparent panels of the display panel
2. Although it amounts to only 3% of the total radiation that
reaches the earth, UV radiation is energetic enough to cause
chemical reactions, weathering of polymers, and fading of certain
dyes. Wavelengths in the UV-B range of 290 315 nanometers cause the
most photochemical degradation. To counter such degrading effects
on both the display panel and the display materials inside,
selection of an appropriate acrylic sheet material, for example,
colorless Acrylite.RTM. FF sheets, which allow very small amounts
of UV light transmission below 345 nanometers, may be
desirable.
Each of the components of the display panel 2, excepting the left
spacer member 20, is solvent welded to adjacent components of the
display panel 2. An exemplary solvent may include methylene
chloride, which is applied to adjacent surfaces of the components
of the display panel 2 either directly or through capillary action
as is well-known in the art. As the components of the display panel
2 are held together, the acrylic material of each of the components
fuses with adjacent material as the solvent dissipates over time.
In this manner, each of the top spacer member 16, right spacer
member 18, and bottom spacer member 22 is welded between the rear
transparent panel 12 and the front transparent panel 14. Similarly,
the front frame member 8 is welded to the front surface of the
front transparent panel 14 and the rear frame member 10 is welded
the rear surface of the rear transparent panel 12. By solvent
welding along the entire length of each of the top spacer member
16, right spacer member 18, and bottom spacer member 22, a cavity
62 with water-tight walls and an open end is formed by these spacer
members between the front transparent panel 14 and the rear
transparent panel 12.
As seen to good advantage in FIG. 11, the left spacer member 20 is
friction-fit within a spacer gap 58 between the front transparent
panel 14 and the rear transparent panel 12. The left spacer member
20 provides a substantially weather-resistant seal against the only
opening into the cavity 62 between the front transparent panel 14
and rear transparent panel 12. The left spacer member 20 may be
further secured in place via spacer bolt 32 inserted within the
spacer bolt holes 46 of the components of the display panel and
secured by a spacer nut 34. The left spacer member 20 could
likewise be secured by any other appropriate fastening device, for
example, a pin, a plug, a clasp, a lock, or other fastener.
The display panel 2 may be mounted to the canopy supports 6 of the
golf cart 4 via a pair of support clamps 24. Each support clamp 24
may be a single metal web bent into a shape that fits snuggly
around the cross-sectional shape of the canopy support 6. In the
embodiment depicted, for example, in FIGS. 1, 2, 4, and 11, the
support clamps 24 are generally square in shape to fit around a
square cross-section canopy support 6. The support clamps 24 are
formed such that the ends of the metal web are positioned adjacent
to each other and define a front clamp tab 36 and a rear clamp tab
38 extending parallel to the front face of the canopy support 6 and
orthogonal to the interior face of the canopy support 6. The front
clamp tab 36 and the rear clamp tab 38 each define an aperture that
is concentric with the other aperture.
The front clamp tab 36 and the rear clamp tab 38 of the support
clamp 24 are aligned with either the right clamp bolt hole 40 or
the left clamp bolt hole 42 depending upon the side of the display
panel 2 on which the support clamp 24 is mounted. Clamp bolts 28
are inserted through the right clamp bolt hole 40 and the left
clamp bolt hole 42 and then through the apertures in the front
clamp tab 36 and rear clamp tab 38 of the support clamps 24. The
clamp bolts 28 further secured with nuts 30 in order to secure the
support clamps 24 to the display panel 2.
It should be noted that the support clamps 24 should be
sufficiently flexible in order to open a gap between the front
clamp tab 36 and rear clamp tab 38 to fit around the canopy support
6, while also resilient to then return to the preferred shape to
fit snuggly around the exterior surface of the canopy support 6. In
order to and insure a tight friction-fit around the canopy support
6 and thus prevent any movement of the display panel 2, the support
clamp 24 may be covered with or coated by a grip-sleeve 26. The
grip-sleeve 26 may be made of rubber or other similar minimally
compressible weather-resistant covering or coating with a good
co-efficient of friction against the metal canopy support 6.
In an alternate embodiment (not depicted), the display panel may be
attached to the canopy supports using a second pair of support
clamps mounted along the bottom edge of the display panel, one at
each lateral end. The second set of support clamps may be identical
to the support clamps 24 and may be fastened to the display panel
using bolts inserted through additional holes in the bottom edge of
the display panel. In another embodiment (not shown), the support
clamps may be in the form of sleeves extending the entire height of
the display panel. The sleeve may be formed in the same
cross-sectional shape as the canopy support in order to fit tightly
about the canopy support. The sleeve may have clamp tabs extending
along its length and may be attached to the display panel with
bolts, in a similar manner as the support clamps 24, to both the
top and bottom edges of the display panel. In yet a further
embodiment (not shown), the support clamps may additionally have a
tightening mechanism to increase the tension of the support clamps
about the canopy supports. Exemplary tightening mechanisms may
include a worm or screw drive similar to a hose clamp or a ratchet
mechanism, each of which would operate to further tighten the
support clamps against the canopy supports. Each of these alternate
clamp designs may be desirable in order to ensure the display panel
is firmly mounted to the canopy supports.
FIG. 12 depicts the insertion or removal of a display sheet 60 of
identification, informational, or advertising material that resides
within the cavity 62 of the display panel 2. In order to insert a
display sheet 60 into the display panel 2, the spacer nut 34 is
loosened from the spacer bolt 32 and the spacer bolt 32 is removed
from the spacer bolt hole 46 in the display panel 2. The left
spacer member 20 may then be grasped by a user's fingers via the
tab recess 44 in the display panel 2 exposing the outer edge of the
left spacer member 20. Once the left spacer member 20 is removed,
access is provided to the cavity 62 by a gap 58 between the front
transparent panel 14 and rear transparent 12 of the display panel
2.
The display sheet 60 may be printed on a front side with
identification material, for example, the name of a golf course,
and on the rear side with advertising and/or informational
material, for example, advertisements directed at golfers or
information about the golf course. The display sheet 60 may be
sized to such rectangular dimensions as to both fit within and fill
up the cavity 62. In this manner, the identification,
informational, or advertising material maybe seen within the
display panel 2 through both the rear transparent panel 12 and the
front transparent panel 14. The display sheet 60 is preferable
printed using UV resistant ink to reduce the potential for the
printed material on the display sheet 60 from fading due to
extending exposure to the sun.
It should be recognized that the cavity 62 may be provided with two
display sheets, one for viewing out of the front transparent panel
14 and a second for viewing through the rear transparent panel 12.
For example, a first display sheet may be considered a "permanent"
display sheet with a name and insignia of the golf course exposed
through the front transparent 12 while a second display sheet may
be provided for viewing through the rear transparent 12 may be
regularly replaced in order to change or update the advertisements
or information. By maintaining a static display sheet viewable
through one of the transparent panels, printing costs for
replacement display sheets may be reduced.
Once the display sheet 60 is inserted into the cavity 62, the left
spacer member 20 may be inserted into the gap 58 between the rear
transparent panel 12 and the front transparent panel 14, creating a
weather resistant seal. The spacer bolt 32 may then be reinserted
into the spacer bolt hole 46 and fastened with the spacer nut 34.
Should the golf course desire to change the advertising or
information in the display panel 2, the left spacer member 20 may
be removed as previously described, the display sheet 60 extracted
from the cavity 62, and replaced with a new display sheet printed
with alternative information or advertising material.
In an alternative embodiment of the invention, the display panel
may be integrated into the construction of the canopy. Generally,
golf cart canopies are formed of a molded plastic material that is
mounted to the tops of the canopy supports. In this embodiment, the
front edge of the canopy may be molded to extend downward between
the front canopy supports and form a frame. The transparent panels
may then be affixed to the frame in the canopy for accepting and
protecting display material. The display material may be inserted
through an opening on a side of the frame portion of the canopy and
be positioned between the transparent panels.
In a further embodiment of the invention, the display panel may be
integrated into a windshield mounted between the front canopy
supports of the golf cart. Generally, golf cart windshields are
either made of a single sheet of molded transparent acrylic, which
spans that opening between the front canopy supports between the
dashboard of the golf cart and the canopy, or of two sheets of
molded transparent acrylic that are hinged together. A single sheet
windshield may be formed to include a framed cavity at the top of
the windshield adjacent the canopy for insertion of the display
material. In a two-part windshield, one acrylic sheet forms a
bottom half and is fixed to the golf cart between the canopy
supports. The second acrylic sheet is mounted to the bottom sheet
on hinges and may be removably mounted at its top to the canopy
supports adjacent the canopy. The hinges allow the top sheet to
rotate forward and downward to fold against the bottom half of the
windshield. In this embodiment the bottom half of the windshield
may be formed to include a framed cavity adjacent the interface
with the top half of the windshield for insertion of the display
material. In this manner the display material facing rearward
toward the occupants of the golf cart is always viewable and is
exhibited at a height slightly above the steering wheel, while not
obscuring the view of the driver. The display material facing
forward is viewable through the transparent top half of the
windshield when it is folded down against the bottom half of the
windshield as well as when the top half of the windshield is up and
connected to the canopy supports.
